The centering plate is of an improved construction for providing reliable automatic or manual securement of a yarn end during a threadup operation, and comprising a hub extending axially into and supporting one end portion of the carrier tube and an adjoining larger diameter circumferential flange positioned in engagement with the end of the carrier tube. A circumferential yarn securement channel is provided adjacent to the flange and is defined by a pair of opposing surfaces positioned so as to provide a continuously narrowing cross-sectional area in said channel for wedging and securing a yarn therein.</p> |
